Space-borne laser ranging could measure the distance between laser range finder and detection target through the transmitter emitted by a high degree of stability of laser pulse, which related to the design and application of laser. In particular, in order to achieve the function and performance of laser power supply was the most important. Therefore, the realization of the external control and real-time status of the amount of the acquisition become particularly important in space-borne laser power supply. Based on FPGA technology, by use of AC/DC power supply module, remote telemetry components and display control module, a system was designed to provide external signal, Q-signal and AD/DA control signal of the laser power supply, in order to achieve the real-time telemetry of the status of amount of laser power supply, and the real-time adjustment and control of LD current signal and Q-signal. The system could be set to control the laser repetition rate and laser emission times, can also be related to real-time display of the number of the laser repetition rate and laser emission times, could also be related to real-time display of number of the laser pulses and the remote measurement of the laser power supply. At the same time, the design and implementation of the system which involved in laser power supply were described in details, and they would further propose the improvement program of high reliability performance and functionality, in order to enhance remote control and telemetry system of the laser power supply.
